Mark Lancaster: The hon. Gentleman makes an important point; indeed, I will come to the health effects in greater detail shortly. However, let me be absolutely clear that I am pressing for this Government to act in the manner that he suggests.
	In my constituency, there are more than 6,000 Somali residents. One of the leaders of the Milton Keynes Somali community, Adan Kahin, has shared many alarming stories with me. His biggest concern is that khat is at the root of family breakdown, owing to issues such as unemployment, economic hardship or aggression arising from heavy usage. Adan has expressed explicit concern about the number of teenage boys whose fathers are absent from the home, instead spending all day chewing in a mafrishi, or khat house. If the Government are truly concerned about the antisocial behaviour witnessed last summer, it is vital that we shine a light into those corners of society. Adan has warned of usage spreading to female members of the community—women who are left alone all day with large numbers of children and little escape. What links all users, however, is the common belief that turning to khat will alleviate the destitution and stress that permeate their lives. I am even aware of instances in well regarded British institutions where khat has been chewed inappropriately during working hours. There have also been complaints about disturbances caused by delivery of the plant and violence outside mafrishis, with one incident even leading to the death of a seller in my constituency.
	Our hands-off policy means that there is absolutely zero quality control. One box of khat checked by port health at Heathrow contained such high levels of pesticides that it was unfit for human use, and that is just one box out of the 10 million tonnes arriving each week. Because of the lack of information held on hospital admissions,
	we are still uncertain about the overall long-term health effects. Problems range from the need for substantial dental treatment, owing to the quantity of sugar and cigarettes consumed, to more serious conditions, such as liver failure and psychosis. It is clear that health practitioners are clueless about how to advise users. Those wishing for a fresh start are stranded, with little or no support—no addiction services or pharmacological agents who can treat khat dependence. Essentially, there are few ways out.
	The last review of khat surmised that usage is not prevalent. That may be true for the mainstream population, but not for the demographic concerned. It has been put to me that the Government are not interested because this is perceived as a minority issue. I know that this is not the case, but it is in the Minister’s hands to demonstrate to my community that he does care, as actions, as we all know, speak louder than words.
